Trend hit by UPX vulnerability

Compression handling issue affects swathe of products.

A wide range of Trend Micro security products are affected by a flaw in the handling of files compressed with UPX, which could be exploited to shut down the product or even access a machine remotely. An update is available to circumvent the problem.

The buffer overflow vulnerability was pointed out to Trend in mid-January, and has now been disclosed following the release of a pattern file to fix the hole. Affected products include flagship OfficeScan and PC-cillin scanners, as well as various mail and network security products including Linux and NetWare offerings.

Trend's announcement of the problem, along with the fix, is available here. An alert from iDefense is here, and another from Secunia here.

A second and less significant vulnerability, exploitable only from the local system, has also been reported in the Anti-Rootkit module included in several Trend products. This flaw has also been fixed with an upgrade, and details are again available from Trend, iDefense or Secunia. Trend users are advised to ensure both fixes are applied as soon as possible.
